CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. 442,519, dated December 9, 1890.

Application filed May 17, 1890.

To @ZZ ufl/0771, t may concern:

Be it. known that I, ANDREW Geleen, a citizen of the United States, residing at Driftwood, in the county of Pocahontas and State of Test Virginia, have invented a new and useful Churn-Dasher, of which the following is a specification.

This invention has relation to dashers for churns and means for operating the same; and among the objects in view are to provide a twin dasher adapted to operate alternately, means for regulating the length of stroke of the dasher, and for inserting and removing the dasher into and from the churn and for inserting the churn in position to be operated upon by the dashers.

Ylith the above objects in view the invention consists in certain feat-ures of construction hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, Figure l is a perspective of a churn dasher and motor constructed in accordance with my invention. Fig. 2 is a transverse section of the same. Fig. 3 is a perspective in detail of one of the flasher-staffs.

Like numerals of reference indicate like parts in all the figures of t-he drawings.

1 represents a suitable base, from the opposite sides of which rise the vertical stantiards 2, connected at their upper ends by the cross-head 3, and below said head by a crossbar 4, having a central opening 5, from the opposite sides of which rise short bearingstandards 6. Below the transverse bar 4 the vertical standards 2 are provided with vertically-disposed oblong openings or recesses 7, which receive the reduced ends 8 of a transversely-disposed churn-clamping table 9, provided at its center with a rectangular opening 10, the front wall of which is formed by a hinged block 11, hinged to the table 10 by a hinge 12. The edges of the block are of inverted-L shape or rabbeted, as at 13, and take into oppositely-disposed rabbcts formed in the edges of the table.

14 represent opposite dasher staffs or rods of rectangular shape, and of a combined width equal to the openings 5 and 10, in which they are adapted to reciprocate alternately, as hereinafter described. The lower extremities of the staffs are provided with semicircular perforated heads or dashers 15, and above the same are transversely recessed, as at 16',

to receive similarly-shaped removable dasher-heads 17, likewise perforated, which latter heads have a rectangular recess 18 to tit into the recesses 1G of the staffs.

Between the upper ends of the short bearing-standards 6 there is pivoted, as at 18, a 6o rocking lever 19, which at eaelrside of its pivot is 'provided with a series of adjustingholes 20. Near the lower ends of the short standards 6 there is pivoted, as at 21, a rectangular yoke 22, from one end of which projects an operating-lever 23, and from the opposite end of the yoke there projects an arm 24, which by link 25 is pivotally connected to the rear end of the rocking lever 19,50 that -a movement of theoperating-lever 23 causes 7o a similar movement. upon the part of the rocking lever 19.

Hinged to the outer faces of each of the dasher-staffs 14, as at 26, is a connecting-bar 27, said bars being bifurcated for the major portion of their lengths and receiving between their bifurcations the arm 24 and the lever 23, and at their upper ends embracing the rocking lever 19. The bifurcated portions of the connecting-bars 27 are provided with a 8o series of adj Listing-holes 28, which by removable pins are connected to the series of adjusting-holes 20, formed in the rockin g lever 19.

21 represents the churn-body, which is inserted in position in the following manner: The lever 23 is elevated and the turn-button 30 swung from over the free end of the block 11, which is then elevated or swung to one side. The dasher-staffs are then lowered so that their upper ends may be disengaged 9o from the opening 5 of the cross-bar. The ends of the dasherstaffs are now introduced into the churn-body, which latter is forced under the table 9, the table yielding to the upward pressure by means of coiled springs 31, one of which is introduced under each of the tenoned ends 8 of the table and the upper end of the recess 7 These springs serve to force the table down upon the churn-body, and after the ends of the staffs have been reroo inserted in their gnideopenings the block 11 is swungr down to close the recess or opening in the table and the button 30 swung over the same.

The operation of churning may be now carried on, and simply consists in vertically vibrating the operating-lever 23, which by reason ot' the described connections will alternately reciprocate vertically the flasher-staffs 14 and their heads, forcing the milk through the perforations in the heads and from one side of the churn up the opposite vertical half and back again. Such motions upon the part of the dashers have been found by experience to convert the milk to butter in an exceedingly shortA period of time, and by reason of the peculiar arrangement of levers the power required to operate the dashers within the churn is reduced to a minimum.

If'desired, the upper heads may be easily removed from the dasher-staffs, thereby doubling the length of the strokes of the stais, or intermediate adjustments may be secured: by pivoting the upner ends of the bifurcated connecting-bars 27 at varying distancesy from thc pivot-point 18 of the rocking lever 19.

Having thus described my invention, what I claim isl. In a churn-motor, the combination, with opposite standards having opposite slots: and vertical guides, of a table the ends of which are reduced andA terminate in the slots, coiled springs arranged over the ends of the table so as to depress the same, a pair of dasherstaffs mounted for alternate reciprocations-i-n a recess formed iin.: the table, from which they arev laterally removable and terminating in heads, and a, churn-body for receiving the heads and having its upper end yieldingly clamped upon by the table, substantially as specified.

2. 1n a churn-motor, the combination of a suitable frame, a pivoted rocking lever, a lower pivoted operating-lever connected at its rear end tothe rocking lever, a pair of verticallymoving flasher-staffs, and connecting-bars connecting the rocking lever at each side ot its pivot loosely with the dasher-staffs, substantia-lly as specified.

3. In a churn-motor, the combination of a suitable frame, a pivoted rocking lever,a lower pivoted operating-lever connected at its end by a loose link to the locking-lever, a pair of vertically-moving dasher-statfs arranged side by side, and connecting-bars hinged at their lower ends to the dasher-staffs and ad justably connected at their upper ends to the rocking lever at each side of its pivot, substantially as specied. 1

et. In a churn-motor, the combination of a suitable frame, a pivoted rocking lever having adjustable holes, a lower pivoted operatin g-lever having a central yoke, a link pivoted to the rear ends of the rocking lever and the operating-lever, a pair of vertically-reciprocating dasher-staffs mounted in suitable guides in the frame and for movement Within the yoke of the operating-lever, and opposite connecting-bars hinged at their lower end's to the dasher-statfs, bifurcated at their upper ends, and provided With adj listing-holes, and removable pins for connecting the bifurcated ends to the pin-holes ofthe rocking lever, substantially as specified.

5. In: a churn-motor, a churn-body-clamping table, in combination with a frame for the same,said table being provided with a recess, one Wall of which is formed by a hinged block fitting rabbets formed inthe edges of the recess, a turn-button for locking the block, and

` a pair of dasher-statt's mounted in the recess and means for operating the same, substantially as specified.

In testimony that I claim the foregoing as my own l have hereto affixed my signature in presence of two witnesses.

ANDRE W GEIGER.
